WARNING!
Risk of water entry. Close the seawater cocks before
doing any work on the seawater system.
1
Remove the cover from the raw water pump and
remove the impeller.
If the impeller is cracked or damaged it must be
replaced.
2 If the pump shaft can be turned by hand, the flange
must be replaced.
3 Lubricate the pump housing and inside of the cover
with a little glycerin.
IMPORTANT:
The impeller may get damaged if other types of
lubricant than glycerin are used.

Seawater System, Cleaning and
Inhibiting
The raw water system must be flushed with fresh
water, to prevent deposits and salt crystals from
building up inside it. It must also be conserved when
the boat is laid up for winter/out of season storage so
that it is protected from internal corrosion.
